Specification of Letters Patent.

Patented May t, 1913..

Application led July 8, 1914:. Serial No. 849,666.

To all whom t may' concern Be it known that l, ANDREW HAWN, a citizen of the United States, and a resident oi' the city of Goodland, county of Newton, and State-:of Indiana, have invented certain new and useful improvements in Shock- Absorbers, of which the following is a specication. v

invention relates to improvements in absorbers for vehicles, and has for its object the production of a device of this character-which will be of durable and economical construction and elicient in use.

@ther objects will appear hereinaiten The invention consists in the combmatlons and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings forming a part. of this specification, and 1n which,

dll

. Figure 1 is a partially sectional rear clevation of a vehicle equipped with shock absorbing devices embodying-my invention,

Fig. 2 is an enlarged top plan View of one of the leversincluded in the shock aby sorber detached, t

Fig. 3-is a sectional side elevation of one of said levers showing the connection thereof with the base of the vehicle and the leaf spring of thebody of the vehicle,

Fig. 4 is a section taken on line afa-w of Fig. y3, looking in the direction of arrows a-a, and

Fig. 5 is a section taken onv line --x of 3,' looking in the direction of arrows The preferred form of construction as illustrated in the drawings is applied to an lautomobile comprising a body 1 and a wheeled base, the latter comprising axles 2 (one only being shown in thel drawings) and wheels 3 mounted upon said axles. At

, the underside of body 1 is provided the usual bowed' leaf spring disposed transverselyof'said body.

Arising from the base of the vehicle at Seither side thereof are stools 5, the lower ends of which are secured rigidly by bolts 6 to the ends of axles 2; Fulcrumed at 7 tothe uppervend of each of the stools 5 is an inwardlyprojecting lever 8. Each of the levers 8 is plvotally connected intermediate its extremities but adjacent the fulcrum 7 thereof. as at 9 with the adjacent end of spring 4. Said levers 8 are formed at their outer ends with depending spaced lugs, as shown, for the accommodation of the connecting pins employed at the points 7 and 9, as just described.

The inner end of each lever 8 is bent downwardly and is connected by means of a helical tension spring 10 with the under side of vehicle body 1. The connection between the lower end of each spring 10 and the corresponding lever 8 is effected by means of eye bolt 11 which passes through the perforated inner end ofthe lever, being secured to the latter by means of nuts 12.

'In order to afford clearance for the endsof spring 4, in the connection of the latter with levers 8, thelatter are offset as at 13,

as-clearly shown 1n Fig. 2. Also, in order l sure upon said levers will be counteracted by the upward pressure exerted upon the. inner ends of said levers by the springs 10, `the latter therefore indirectly serving to support the vehicle body. By positioning the points 'of engagement of the endso springe with the levers 8, adjacent the ful crums of the latter, so that the distance between said points of connection and the inner extremities of said levers is considerably` greater than the distance between the points 9 and the fulcrums 7, great leverage is developed which permits of comparatively light sprin s 10 being employed. This, of course, resu ts in an economical construction, the springs 10, because of their lightness being of low cost. Also, by reason of the lightness of springs 10, a shock absorber is produced which is very sensitive, being adapted to respond under the smallest shock or jar, and thus conduce to comfort and ease to the occupants of the vehicle, when in use. t

While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capa ble of variation and modification without departing from the spirit of the invention..

llOlll but desire to avail nrvself ot' such variations and n'nnlifications as come within the scope ot' the appended claims.
